Overview

The ABB CT-MFD.12 (SKU: 1SVR500020R0000) is a multifunction electronic time relay from ABB Electrification's CT-D timer range, engineered for precise timing control in industrial automation and process applications. This relay delivers seven distinct timing functions—including ON-delay, OFF-delay, interval, pulse generator, flasher, star-delta change-over, and one-shot—with seven selectable time ranges from 0.05 seconds to 100 hours. This versatility supports both short-cycle operations (e.g., motor starting, valve actuation) and long-duration processes (e.g., batch sequencing, lighting control, HVAC scheduling). The CT-MFD.12 operates reliably across a wide supply voltage range of 24 to 48 V DC or 24 to 240 V AC, eliminating the need for external voltage converters in mixed-voltage systems. Its single changeover (c/o) contact is rated for 250 V and 4 A, providing robust switching capability for inductive and resistive loads. The control input uses voltage-related, non-floating triggering, simplifying integration into existing control circuits without requiring floating inputs. Key applications include motor control (e.g., delayed start/stop, jogging), process sequencing (e.g., conveyor timing, batch processing), lighting control (e.g., timed on/off, flashing signals), and general-purpose timing tasks where accuracy and repeatability are critical. The relay’s compact design (17.5 mm width, 80 mm height, 63 mm depth) and lightweight (0.066 kg) make it suitable for space-constrained control panels. Operating temperature range spans -20°C to +60°C, with storage from -40°C to +85°C, ensuring performance in harsh industrial environments. With RoHS compliance and UL/CSA certified connecting capacity (flexible 1x 18-14 AWG, rigid 1x 20-12 AWG or 2x 20-16 AWG), the CT-MFD.12 meets global safety and environmental standards. Its dual voltage compatibility and extensive timing range reduce the need for multiple specialized timers, offering a cost-effective, space-saving solution for diverse timing requirements in automation, building management, and industrial control systems.

TDB24AL

The TDB Series combines accurate digital circuitry with isolated, 10A, DPDT or SPDT contacts in an 8 or 11-pin plug-in package. The TDB Series features DIP switch selectable time delays ranging from 0.1-10,230 seconds in three ranges. The TDB Series is the product of choice for custom control panel and OEM designers. Operation (Delay-on-Break): Input voltage must be applied to the input before and during timing. Upon closure of the initiate switch, the output relay is energized. The time delay begins when the initiate switch is opened (trailing edge triggered). The output remains energized during timing. At the end of the time delay, the output de-energizes. The output will energize if the initiate switch is closed when input voltage is applied. Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the time delay and output.
